DRAW-BAR FOR PASSENGER-CARS.

SPECIFICATION forming part of Letters Patent No. 444,190, dated J'anuary 6, 1891.

Application filed September 25, 1890. Serial No. 366,141. (No model.)

' To all whom it may concern:

Be it known that l, DAVID WYLIE,a citizen of the United States, residingat Detroit, county of Wayne, State of Michigan, have invented a certainnew and useful Improvement in Passenger Draw-Bars; and I declarevention. Fig. 2 is a side elevation of one of the bars. Fig. 3 is a planview showing the hooks uncoupled. Fig. 4 is an inverted plan, and Fig. 5is a detail View of the locking pin or bolt. R

My invention has for its object a simpler, more efficient, and moreeconomical construe tion of draw-bars for passenger-cars, as well as onemore convenient and satisfactory in its operation.

I carry out my invention as follows:

A represents the customary draw-bar timbers.

B is the customary spring engaged with the rear of the draw-bar.

C denotes my improved d raw-bar, constructed of web C', extendingrearward to engage the spring-yoke B2.

C2 is the draw-bar hook, having a pivotal or jointed engagement with theforward end of the web C, as shown at C3. To this end the forwardextremity of the web is constructed with a tongue c, the hook beingcorrespondingly recessed, as shown at c', to receive the tongue, the pinC3 forming the pivotalunion of the one with the other, allowing the hookto swing laterally about the rounded end of said tongue.

D is a locking-pin to hold the hook in normal position, as'when thedraft is applied thereto. The pin is constructed with a head D', whichin its normal position drops into an orifice E above the rear of thetongue c, between the shoulder c4 of the web and a shoulder c3 on thehook above the recess c. This orifice or recess E is preferably made ofangular form across the bar, the shoulder c3 of the draw-hook and theshoulder c4 of the web being constructed of angular form and' separatedto form said recess to receive the head of said locking-pin. The tongueis constructed with a through-hole at c5 to receive the locking-pin. Thelower shoulder c6 of the hook is preferably made longer than the uppershoulder c3 and recessed, as shown at c7, to receive the forward edge ofthe lower end of the locking pin or bolt, the lower shoulder cS of theweb being provided with a corresponding recess, as at o9, for the rearedge of said pin. The locking-pin is preferably constructed at its lowerextremity with an arm d, forming a sort of a key, preventing theaccidental disengagement of the locking-pin from the tongue.

In Fig. 3 the pin is shown lifted to allow the swinging of the hook.Vhen so lifted, it is evident that a pull upon the hook will canse it toswing about laterally, thus carrying the hooks out of alignment andallowing the hooks of two adjacent cars equipped with my improveddraw-bar to uncouple. observed in viewing said figure that when the hookis swung laterally, as in unconpling, the shoulder c3 rides under thehead of the lifted pin D, supporting the pin and leaving the hook freeto couple. The coupling of two hooks of this construction is effectedsimply by their contact the one with the other,caus ing their respectivehooks to swing backinto normal position, thereby carrying the shoulderc3 out from under the head of the pin D, permitting it to drop and lockthe hooks in normal position. lVhen uncoupled, therefore, two bars ofthis description on adjacent carsare always in position to be coupledwithout further attention by the movement of the car.

To lift the pin D for uncoupling a couple of draw-bars of thisdescription each, is provided with an operating-lever F, suitablyengaged with the pin D. As shown, the web is provided with shouldersff', in which is journaled a spindle F', provided with an arm F2,engaged with the head of the locking-pin.

It will also be 'Ifo this spindle the lever I? is connected. lsythrowing the lever in the proper direction the pin is thus readilylifted.

'llo hold the pin in a lifted position, so that the cars may be drawnapart,l provide, as shown in Fig. 1,a flange f2, which may he castintegrally with the hook, upon which the lever may be supported properlywhen the pin is lifted, the support being of such a nature as not tointerfere with the dropping of the pin when the cars are to be coupledtogether. By

easti ng the supporting-tlange upon the lower portion of the hookitwillbe seen that when the hook swings about in nneoupling the tlangeis carried away from in under the lever, allowing the pin to drop whentwo bars come together for coupling. The hook may he re` cessed, asshown at G, to receive an ordinary coupling-link, and perforated, asshown at G', to receive an ordinary coupling-pin, when it is desired tocouple a car equipped with my invention with a car provided with onlythe ordinary coupling link and pin.

At the rear end of the web the customary connection of the spring 1Stherewith causes a very considerable wear, draw-bars being ordinarilyprovided with an eye cast integrally therewith for the engagement of thespringyoke. B2 therewith. \Vhen the eye becolncs worn too much, thewhole draw-bar is made useless and must be replaced. To this end Iprovide, preferably, a wrought-iron tail-piece II, constructed with aneye to engage the spring-yoke B2. This tail-piece I engage reversiblywith the d raw-bar in any proper inanner, so that when too much wornsimply the tail-piece needs to be replaced. As shown, the tail-piece isconstructed with a shank ll passed through a crosspicce Q in the rearend of the web, said shank being' provided with a key Il2 to lock it inposition. By removing the key the tail-piece may be removed and readilyreplaced, thereby effecting a verygreat saving in expense. Thesimplicity and efficiency of this method of construction are apparent'.

The pin I) may readily be operated from any desired position by acorresponding form and position of the operating-lever. The inatter oflifting the locking-pin would ordinarily be attended to at the same timeas the uncoupling of the air-brake pipes, and for this reason theoperating-lever F is shown in a. convenient position for that purpose. Ido not, however, limit. myself to any specific construction andarrangement of the operatinglever, as I contemplate any suitableoperatinglever as coming within the scope of my invention.

)Iy improved bar will couple readily with any hooked draw-bar with equalfacility as with a companion bar of like constrnction--a matter ofconsiderable importance.

lfhat I claim as my invention isi. In a d1aw-ba1,the combination of theweb, the hook jointedly engaged therewith, and a locking-pin constructedwith an angular-shaped head extending angularly across the web at therear of the hook, substantially as described,

2. In a draw-bar, the combination. of a web provided with a tongue, ahook recessed to receive said tongue and jointedly engaged therewith, aheaded locking-pin engaged in the web at the rear of said hook, and anoperatinglever to raise the bolt, substantially as described.

3. In a draw-bar, the combination of a web, a hook jointedly engagedtherewith and provided with a shoulder c, a locking-pin located in saidweb at the rear of said hook, and an operating-lever connected with saidpin, the construction and arrangement heilig such th at when the bar isin an unlocked position said shoulder c3 will ride under the head ofsaid bolt and support the pin in a position to permittho coupling of thehook, substantially as set forth.

4.-. In a draw-bar, the combination of the web, the swinging hook, theoperating-lever, and a locking-bolt, said bolt constructed with anangular-shaped head. and an arm f7., substantially as set forth.

In a draw-bar, the combination, with a web constructed with a tongue anda shoulder, of a swinging hook constructed with a shoulder c and alockingbolt having an angularly-shaped head located between saidshoulders in its normally-locked position, said shoulder cS riding undersaid head in uncoupling the hook, substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.

DAVID WYLIE.
